AXLE OR SHAFTING GUARD.

Specification of Letters latent.

Patented May 22,1917.

Application filed Jul m, 1916. Serial no. 109,820.

To all whom it may concern:

Be it known that I, PEARL E. TARLTON,

a citizen of the United States,residing at will enable others skilled in the art to which it appertains to make and use the same.

' The primary object'of this invention is to prevent the escape of lubricant from the '15 ends of the axle casing of an automobile,

and passing the packing that surrounds the axle and interposed between the ends of the casing and the hubs of the rear wheels.

A further object of the invention is to prevent any vertical and lateral motion of the axle, with res ect to the casing, from loosening the pee 'ng from snug engagement with the axle.

Another object of the invention is the provision of simple, durable and efiicient means for carrying out the above objects, and which can be conveniently associated with v the axle casing.

Other objects will appear and be better understood from that embodiment of my invention of which the following is a specification, reference being had to the accompanying drawing forming a part thereof, in which:

Figure 1 is a detail'longitudinal sectional view, taken through one end of the axle casin and the hub of the adjacent rear whee of the vehicle, showing the invention associated therewith, and

Fig. 2 is a perspective view of the invention detachedfrom operative position.

Referring to the drawing in detail, the letter A designates one end of the casing for the rear axle of an automobile, or other vehicle, and Ba portion of the axle which extends through the casing and has one end extended beyond the adjacent end of the casing for the accommodation of the hub C of the adjacentrear wheel, and the letter D designates the usual type of roller bearings mounted within the casing and engaging the axle.

As shown in Fig. 1 of-the drawing, the end of the casing A is spaced from the hub C of the wheel, and interposed between the mentioned end of the axle and the hub is a cage 1, which consists of a cylindrical or cup-shaped body that encircles the axleandhas the sides thereof arranged in spaced relation with the axle. The inner end of the ca e is closed by means of a wall 2, which 1s formed integral with the inner end of the cage, and is concentrically provided with an opening for the passage of the axle, and the other end of the cage is closed by means of a removable disk 3, which, like the inner end wall 2 of the cage, is concentrically provided with an opening for the passage of the axle. The disk 3 fits within the outer end of the cage, and is rovided with a peripheral flange 4, which rictionally engagesthe inner surface of the cage, so as to hold the disk in operative positlon. The cage 1 is provided with a circular fiangle 5, that is located at a point adjacent t e inner end of the cage, and which flangle is provided with a peripheral groove 6, t e walls of which groove extend in outwardly diverging relation, as shown more particularly in Flg. 1 of the drawing.

A cylindrical body 7, formed preferably of leather, has one end fitted over the end of the axle casing and clamped thereon by means of a clamping band 8, and the opposite end of the body 7, which is of a diameter larger than the diameter of the firstmentioned end, is engaged over the flange 5 and pressed into the groove 6 and held therein by means of a clamping ring 9.

A pacln'ng body 10 of circular configuration, and formed of felt or other suitable material, is located within the .cage and clamped between the inner wall 2 and the disk 3, and is rovided with a central opening which receives the axle B, and the walls of the opening in the body 10 snugly engage the axle.

The inner face of the hub C is provided with an annular groove 11, which receives the circular body 12 formed of felt, or similar material, and the outer face of the body 12 engages against the adjacent end of the cage 1, and by virtue of this engagement the outer face of the body 12 is depressed at the point of contact with the end of the cage, as shown in Fig. 1, so as to form a tight joint between the body 12 and the adjacent end of the cage.

During rotation of the axle, the cage 1, disk 2, body and packing 10 remain stationa that is a ainst rotation. When any latera or vertica movement is imparted to mitted by the flexible body 7. Suchmovebody 10,

ment of the cage'and the packin the axle,

in the direction of movement 0 prevents the axle, when moved eitherin a vertical or lateral direction, from exerting strain on the walls of the opening in the packing body, thereby preventing the open- 1ng being made larger which would result in the escape of lubricant therethrough.

It will, of course, be understood that while the invention is shown applied only at one end of the casing A, this is for illustrative purposes only, as both ends of the casing will be equipped alike.

It is evident that various changes might be resorted to in the construction, form and arrangement of the several parts wlthout departing from the spirit and sco e of my invention, hence I do not wish to imit myself strictly to the structure herein described and claimed.

'Having thus described my invention what I claim as new, is:

1. The combination with an axle and a casing therefor, and a wheel carried by the axle, of a hollow body located at one end of the casing and encircling the axle, a packing body secured within the hollow body and engaging the axle, and a flexible connection between the body and the casing, for the purpose specified,

2. The combination with an axle and a casing therefor and a wheel carried by the axle, of a hollow movable body located at one end of the casing and encircling the axle, a packing body secured within the hollow body and engaging the axle, and a body carried by the inner face of the,- hub of the wheel and formed of comparatively soft material and engaging the outer end of the hollow body, for the purpose specified.

3. The combination with an axle and a casing therefor, of a low body encirclingthe axle and located at one end of the casing, of a circular'fiange casing therefor, and a packing carrying holcarried by the body and having a groove, a

flexible element having one end secured to the casing and its opposite end received by the groove in the flange, and a retaining ringof the casing, and a clamping ring detachably connecting the hollow body to the easlng.

5. The combination with an axle and a acking carrying hollow body encircling t e axle and located at one end of the casing, a flange formed at one end of the hollow body and provided with a roove, a second hollow body formed of flexible material having one end secured to the casing and its opposite end engaging over the flange on the first-mentioned hollow body and extending into the groove in the flange, and fastening means positioned within the groove in the flange and engaging the adjacent end of the second mentioned hollow body.

6. The combination with an axle and a casing therefor, of a hollow movable body encircling the axle and carried by one end of the casing, packing located within the body and engaging the axle, a disk fitted within one end of the body and engaging the packing and provided with an opening for receiving the axle, and a peripheral flange formed on the disk and frictionally engaging the inner surface of the hollow body for securing the disk within the hollow body.

In testimony whereof I aflix my signature in presence of two Witnesses.
